Description

Technical Field

[0001] This utility model relates to the field of multi-wire cutting technology, specifically to a material plate locking device for a large multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines use the high-speed reciprocating motion of metal wires (cutting wires) to carry abrasive particles into the processing area of ​​the material to be cut, simultaneously cutting the workpiece into hundreds or thousands of thin slices. They offer advantages such as high efficiency and low material loss. Before cutting, the multi-wire cutting machine requires a material bonding process, where the workpiece is adhered to a material plate, which then mounts the workpiece onto the worktable. With the widespread application of multi-wire cutting technology, the size of the workpieces being cut is trending towards larger dimensions, leading to the development of table-mounted oscillating multi-wire cutting machines. (See attached image) Figure 1 The large workpiece 1 shown is cut by a worktable swing-type multi-wire cutting machine. The workpiece 1 and the material plate 2 are pushed into the cutting chamber by the horizontal propulsion mechanism of the loading and unloading system, and are hoisted above the cutting wire mesh with the material plate clamping rail 3 on the swing worktable. The front end position of the material plate 2 is limited by the limiting element set on the worktable. In order to ensure the stability of the material plate 2 and the workpiece 1 during the cutting process and improve the cutting quality, the material plate locking surface 2-1 at the rear end (free end) of the material plate 2 also needs to be locked and fixed by the wedge locking mechanism.

[0003] Currently, for ordinary oscillating multi-wire cutting machines, the wedge is usually used manually to lock and fix the material plate directly. However, for large-scale oscillating multi-wire cutting machines, the horizontal feeding mechanism of the material plate in the loading and unloading system not only restricts the working space, but also prohibits operators from working under the horizontal feeding mechanism of the material plate according to the equipment's operating procedures. Therefore, it is imperative to design an innovative material plate locking device for large-scale multi-wire cutting machines. Utility Model Content

[0004] This utility model provides a material plate locking device for a large multi-wire cutting machine. It aims to lock and fix the free end of the material plate through the cooperation of a lifting seat, a locking actuator and special tools, using a remote operation method, so as to ensure the personal safety of the operator and the stability of the workpiece cutting process, and improve product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material plate locking device for a large multi-wire cutting machine is provided, comprising a fixed frame, a lifting seat, a locking actuator, and special tools;

[0007] The fixed frame is installed on the lifting body of the multi-wire cutting machine, and a lifting seat is mounted on the fixed frame. A locking actuator is arranged on the lifting seat.

[0008] The locking actuator includes a locking wedge, a locking pressure plate, a locking bolt, a wedge bracket, and a bracket push plate. The wedge bracket is placed on a lifting seat and fixedly connected to the bracket push plate. The wedge bracket can be moved back and forth by pushing and pulling the bracket push plate. The locking wedge is placed on the wedge bracket. The front end of the locking wedge is an inclined surface that mates with the locking surface of the material plate. A material plate clamping track insertion groove is provided on the locking wedge. The locking pressure plate is arranged between the wedge bracket and the locking wedge. Its central axis coincides with the central axis of the material plate clamping track insertion groove of the locking wedge. The locking pressure plate is fixedly connected to the material plate clamping track by the locking bolt.

[0009] The special tools include a long-handled wrench and a wedge push-pull bolt. The long-handled wrench is used to tighten the locking bolt, and the wedge push-pull bolt can pass through the wedge bracket and connect to the locking wedge.

[0010] In the aforementioned large multi-wire cutting machine material plate locking device, the inclined iron bracket is an L-shaped bracket in the locking actuator. Its vertical wall outer side is fixedly assembled with the bracket push plate, and a pressure plate assembly groove is provided on its vertical wall inner side. The locking pressure plate is placed in the pressure plate assembly groove of the inclined iron bracket.

[0011] The aforementioned large multi-wire cutting machine material plate locking device has a limiting groove and a limiting hole on the bottom surface of the lifting base that cooperate with the locking actuator; the limiting groove is a rectangular groove, and the front and rear edges of the rectangular groove limit the extreme position of the forward and backward movement of the inclined iron bracket.

[0012] In the aforementioned large multi-wire cutting machine material plate locking device, the bracket push plate in the locking actuator is an L-shaped push plate, which is arranged below the lifting seat. Its vertical wall passes through the limiting groove on the bottom surface of the lifting seat and is fixedly assembled with the inclined iron bracket. Positioning holes are provided on the horizontal wall of the L-shaped push plate. Two sets of positioning holes are arranged in the front and rear. The two sets of positioning holes are respectively fixed to the front and rear positions of the inclined iron bracket by cooperating with the limiting holes on the bottom surface of the lifting seat through positioning pins.

[0013] In the aforementioned large multi-wire cutting machine material plate locking device, the wedge push-pull bolt is a long rod bolt, the wedge bracket is provided with a wedge push-pull bolt through hole, and the locking wedge is provided with a threaded hole that mates with the wedge push-pull bolt.

[0014] The aforementioned large multi-wire cutting machine material plate locking device includes a long-handled hexagonal wrench with a through hole on the inclined iron bracket, and a countersunk hexagonal bolt with the locking bolt matching the long-handled wrench.

[0015] The aforementioned large multi-wire cutting machine material plate locking device has lifting grooves on the two side columns of the fixed frame and lifting rails on the outer side wall of the lifting seat, with the lifting rails passing through the lifting grooves.

[0016] This utility model provides a material plate locking device for a large multi-wire cutting machine. It can switch between the material plate locking operation position and the non-operation position through the cooperation of a lifting seat and a fixed frame. When the material plate and workpiece enter the cutting chamber through the horizontal propulsion mechanism of the multi-wire cutting machine's loading and unloading system, the lifting seat drives the locking actuator to rise to a set height, clearing the material plate and workpiece passage. After the material plate and workpiece are in place, the lifting seat drives the locking actuator to descend to the material plate locking operation position. First, the inclined iron bracket is pushed to the set position by the bracket push plate, and then the locking inclined iron is pushed to the position where it fits against the material plate locking surface by the inclined iron push-pull bolt. Then, the locking bolt is tightened using a long-handled wrench, and the inclined surface of the locking inclined iron is pressed and fixed to the material plate locking surface by the locking pressure plate. This allows for remote operation outside the cutting chamber of the multi-wire cutting machine to lock and fix the free end of the material plate, ensuring operator safety, workpiece cutting process stability, and improving product quality.
